I Don’t Want to Win Lying Down

this...

Is this serious?

Everyone present was deeply suspicious of this.

To put it bluntly, although this is just a password guessing game, most people regard it as a probability challenge.

certainly,

The methods adopted by the people are not the same. Some people use probability limit theory, while some people use probability distribution, that is, the probability properties of random variables, and some people go too far and use Markov process to study the state of discrete event dynamic system space problem.

but,

The probability of all four-digit passwords appearing is equal to 5,000.5 times.

After that, everyone began to expand, because this is a four-digit password set artificially. From the perspective of human thinking, the probability of appearing a four-digit password is no longer equal, and the number of attempts will be greatly shortened.

Thereafter,

The small password cabinet has become a carnival for many mathematical geniuses and teachers, who are swaying their youth in probability theory.

result...

come out alone

He came up and ended the carnival of probability theory.

...

...

...

Is this a random event?

How else is it possible? !

say,

who is he?

at the same time,

The one who was the most angry was Yang Xiaoman, she felt that she had been tricked and cheated miserably by this guy.

Yang Xiaoman: (#￣～￣#)

So angry!

I was actually cheated!

Let you pay a terrible price at night!

well?

You... You seem to be Xu Mang, right? A certain student present recognized Xu Mang,

He was a member of the representative team from Zhejiang Province. He once fought against Xu Mang in the Zhejiang Provincial Mathematical Olympiad, and then lost completely... Xu Mang's face has been remembered since then.

...

I'm not! Xu Mang shook his head hastily, My name is Xu Yang!

you...

Aren't you Xu Mang? The student asked suspiciously, Why do you have a face like Xu Mang's who deserves to be punched?

I...

You guys are too much!

Hearing this student's words, Xu Mang almost lost his temper. This young man actually suffered from such severe cataracts. He obviously had a beautiful face, but in his eyes, he deserved a beating. Face, I'm afraid it's not an advanced stage of cataract, right?

You'd better go see an ophthalmologist. Xu Mang said seriously, I'm afraid you'll be blind tomorrow!

words fall,

The student shouted excitedly: You are Xu Mang! There is no one more cheap than you in the world with this vile energy in you!

Xu Mang?

He is Xu Mang?

By the way, who is Xu Mang?

Most of the people didn't know Xu Mang. After all, Xu Mang had only made some achievements in materials science and physics, but he had never made any achievements in the field of mathematics. Beijing and Zhejiang Province.

And the capital city is quite special, because the experimental site of the material science database is chosen in the capital city and Shanghai, and the colleges and universities in the capital city have more or less heard of Xu Mang.

Others... sorry, I really don't know!

Student, how did you calculate the password once?

What theory is used?

Is it a coincidence?

moment,

Xu Mang was surrounded by a group of people, and he was a little confused at this moment.

Well...

Actually, I didn't think about the probability of passwords with mathematical thinking. Xu Mang said cautiously, I used behavioral logic in psychology to think about the possibility of passwords, which has nothing to do with mathematics.

Excuse me...

I cheated. Xu Mang said embarrassingly: In the face of such possible situations, no matter how you calculate objectively, the final answer is the same, unless subjective consciousness is added.

And I gave up objectivity and chose subjectivity. Xu Mang said, Consider the problem from the logical behavior of people, add a little deduction of my own, and finally come up with a correct password.

at this time,

A teacher leading the team asked: I have also considered subjectivity, but I need a reference condition, and this locker only has the password, and I don't know any other information. How can I find a valuable subjective consciousness?

This is everyone's doubts. There is a lack of a reference, and thus a condition.

Xu Mang smiled, and said silently: You may not have noticed the wear on the password keys, I just made an inference based on the wear and tear.

Wear condition?

don't even say,

If you look closely, it's actually a little dark.

but,

You can't find it unless you look closely. How did he see it?

No!

You haven't been close to the password cabinet before, how did you find this problem? A certain student said, I couldn't even find it when I was standing so close.

Because you are a top student!

And I used to be a scumbag! Xu Mang suddenly felt a long-lost pride in being a scumbag.

slacker student,

Possessing an innate special ability, their eyesight is very good. With a gap of one meter, the students can use the opportunity of a glance to perfectly copy the answers on the examination papers of nearby students.

indeed,

You can't find it unless you look carefully, but with nearly ten years of experience, Xu Mang can accurately distinguish the color difference of the paint on the buttons.

have to say,

Sometimes learning scumbag experience is quite useful.

only...

The people present were a little confused by Xu Mang's answer. Can this scumbag be related to eyesight?

After this,

This group of extremely boring mathematicians, including Xu Mang, started a heated debate on whether mathematics can achieve perfect axiom deduction and whether it can guarantee that there are no internal contradictions.

At present, mathematics has limitations of axiomaticization, and some procedures of mathematical proofs cannot be confirmed to be consistent with the procedures of formal axioms.

In the case of a password locker,

It is impossible to obtain a perfect answer with pure mathematics, but a perfect solution can be obtained by relying on human subjective thinking, but this solution cannot be expressed in mathematics.

therefore,

This group of boring mathematicians has formed two parties. One way thinks that mathematics cannot achieve perfect axiom deduction, and some problems must have internal contradictions, while the other side believes that mathematics will definitely achieve perfect axiom deduction in the future without contradictions.

The two sides began to compete with each other, and there was even the possibility of fighting.

Finally Xu Mang stood up.

In his philosophy, it is impossible for human wisdom to be replaced by a complete formula. For example, he used behavioral psychology to crack the password cabinet. There is no formula to express it.

therefore,

For formal systems, provable can be realized mechanically, but true requires further thinking to consider.

Provable propositions must be true, but true propositions are not necessarily provable.

It's a pity...Xu Mang's remarks didn't have any effect. Instead, the conflict between the two sides spread further, and they almost didn't really fight...

soon,

The crowd dispersed in displeasure, but Xu Mang's troubles had just begun.

Hey hey hey!

I'll take care of the money at home from now on. Xu Mang looked at Xiaoman with a sullen face, and said triumphantly, You have to learn how to do laundry, cooking and mopping the floor, you understand? Otherwise, you'll be deducted the money you bought for cosmetics. !

snort!

Say it again, who is in charge of the money? Yang Xiaoman said disdainfully, Did I promise you anything?

Xu Mang: Σ(°△°|||)︴

not good!

Xiaoman is planning to turn his face and deny anyone!

what to do?

I...

I have a recording. Xu Mang turned on the recording on his phone, and then there was a clip of Xiaoman boasting.

but,

In the face of iron-like evidence, Yang Xiaoman remained unmoved, and said calmly: This is fake!

Xu Mang shrank his head. He knew that Xiaoman was planning to renege on the debt, but there was nothing he could do. Who would let him beat her...

Think about my mother,

Think about your lucky money in the past, save it for you first, and ask your mother to get it if you want it.

I went to get the money the next day, but was asked back, do you have any lucky money?

well...

woman!

What about my two nights a week? Xu Mang asked, Does it count?

What do you think? Yang Xiaoman said proudly.

...

Xiaoman? Xu Mang said painfully, Is your dad living in dire straits all day long?

...

Finally waited until Xiaoman came on stage,

Xu Mang was still brooding about the past. He thought he had played a trick on Xiaoman, but in the end Xiaoman had tricked him.

It is said that love makes women stupid, and it was true in the past, but recently I found that Xiaoman is getting smarter and smarter, and I feel like I want to be a queen...

Xu Mang sighed, silently took out his phone, opened Hearthstone, and charged 10,000 yuan in anger.

Open the card pack!

Only the golden legend can save his fragile heart.

ordinary!

ordinary!

rare!

It was on and on, and the card pack in front of him was almost finished, and Xu Mang's heart gradually became fragile.

Wow! Gold...ordinary.

Xu Mang: wdnmd

quit,

uninstall.

Xu Mang bid farewell to Hearthstone from then on.

Taking advantage of this boring time, Xu Mang began to think about upgrading the material science database. In fact, technology is not a problem, but the problem is not enough money... Deputy Director Zhou just made a request that required a lot of capital investment.

Logically speaking, the money will be issued by the scientific research department, but a sum of money has just been issued, and it has not been a month, and the money is not enough... It seems a bit excessive.

or...

Raise the price?

Xu Mang considered the price increase of the software to charge research and development fees. First of all, from the perspective of morality and law, the price increase is a matter of course. The software itself is used to serve customers. Now in order to improve the service quality, the price increase can also break the law. Come?

Second,

The upgrade of the database was proposed by the deputy director of the Department of Materials Science and Technology of Tsinghua University, and it was not for no reason. This is a passive upgrade, and it is also a forced upgrade.

Combining the above two points, the money comes from Qing University!

But who will pay for Tsinghua University... let them figure it out by themselves.

Thinking of this,

Xu Mang called Deputy Director Zhou, and the two had saved their numbers before.

Hello?

Director Zhou! Xu Mang said seriously, I suddenly remembered something. You want me to upgrade the database. I thought about it... The technical aspect is not a problem, but who will pay for it?
